The quality of fish oil is determined by some parameters such as primary and secondary grade oxidation, fatty acid profile and physical qualities which include viscosity, density, color and clarity. Sardine fish oil by-products of fish meal processing can be a source of polyunsaturated fatty acids (PUFAs), particularly<br />eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Degumming is one of steps that can be carried out to improve the quality of sardine fish oil. The processing will help to reduce oxidation and eliminate the impurity of the oil that influence the quality of fish oil. The purpose of this study was to determine the effect of sodium chloride solution degumming on the quality of sardine fish oil to fulfill International Fish Oil Standard (IFOS). Fish oil purification was done by degumming of 5% H2O,  followed<br />by sodium chloride solution with ratio of fish oil and sodium chloride solution were 1:1; 1:3, and 1:5. The sodium chloride solution concentrations of 5% and 8% for 20, 30 and 40 minutes. The next steps after degumming process were followed by alkali neutralization and bleached by absorbent. The best treatment<br />was at  concentration of 5%  sodium chloride solution, ratio fish oil with sodium chloride solution 1:1 on a long time degumming processed 20 minutes. The best quality of fish oil, according to IFOS, was resulted from the treatments combination of free fatty acid 0.21±0.00%, peroxide value 0.43±0.06 mEq/kg, anisidin <br />value 2.22±0.04 mEq/kg and total oxidation 3.11±0.14  mEq/kg.<br /><br />

Tilapia is a farmed commodity of freshwater fish that can be processed into refined products, e.g. the tilapia fillets. The arising problem in the utilization of tilapia into processed products is its residual waste. The purpose of study is to obtain fish oil from tilapia by-products by wet rendering extraction; to characterize fish oil; to determine the optimum temperature and period of wet rendering extraction; and to determine the fatty acid composition of fish oil. Extraction temperatures were varied i.e. 25, 50, 70, and 90 °C. Extraction periods observed were 15, 25, 35, and 45 min. Quality parameters to evaluate the performance of fish oil were free fatty acid, acid value, peroxide, p-anisidine, total oxidation, and fatty acid composition analysis. The optimum temperature and period of wet rendering extraction were 70 °C for 35 minutes, with the highest yield of 6.44%. Fish oil yield which was obtained using Bligh and Dyer method was 8.12%. Fish oil extracted from wet rendering method contained 1.15% of EPA and 1.03% of DHA. Keywords: by-product of tilapia (Oreochromis niloticus), extraction, fish oil, temperature, time

The purpose of this research is to figure out the effect of processing temperature difference in the processing of crude fish oil below or at 85 °C from gill-less Mackerel fish head using the simple steam jacketed method on the quality of the processing products. This research is also intended to figure out the temperature and duration for the processing which produces the crude fish oil to fulfill both national and international quality standard.The research materials were gill-less Mackerel fish heads. The research was conducted using laboratory experimental method. The experiments were designed into Randomized Block Design with difference temperatures (85 °C, 75 °C, and 65 °C). Each of the temperature treatments was made in triplicate. The quality variables to be observed were free fatty acid value, peroxide value, iodine value, moisture content, yield and sensory value. The quality variables which made the best treatment was then tested using the fatty acid profile test for the best crude fish oil product. The data obtained were analyzed using ANOVA, and the difference among the treatments were tested using HSD test.The research result showed that the temperature difference in crude fish oil processing from gill-less Mackerel fish heads using the simple steam jacketed method gave significantly different effect on free fatty acid value, peroxide value, iodine value, and yield. However, did not give significantly different effect on sensory value.

In this work, lipase from Candida rugosa (LCR) was used as a catalyst for the transesterification reaction of fish oil with methanol. The research process consists of three stages: determine the material properties and the activity of the enzyme from Candida rugosa, transeter of fish oil with methanol catalyzed by the enzyme lipase, evaluation indicators of the quality of biodiesel obtained. Fish oil contains 62% unsaturated fatty acid, acid value of 2.2 mg KOH/g. Activity and specific activity of enzyme were respectively 1064 U/mg enzyme and 2782 U/mg protein. Factors affecting the efficiency of conversion of fatty acid methyl esters - FAME were investigated: the molar ratio of methanol/fish oil, ratio of enzyme/fish oil, temperature reaction, pH reaction, concentration of buffer and reaction time. Yield of biodiesel conversion was 92.65% with optimal conditions: rate of methanol/fish oil was 4:1, the ratio of enzyme/substract was 2%, reaction temperature was 40°C, additional 10% buffer solution pH 7 with 96 hour response time. Products biodiesel obtained FAME components accounted for 98.94%; density at 15°C is 0.8816 g/ml; no free water and glycerine, consistent with the original standard biodiesel (B100) (TCVN 7717:2007). However, the acid value of 1.7 mg KOH products/g higher than the allowable value.

Edible oils produced and consumed in Burkina Faso often do not meet established standards. The objective of this study was to evaluate the total gossypol level of refined cottonseeds oils and the oxidation state of crude peanut oils and refined cottonseeds oils in Burkina Faso to determine the impact on consumer health. A total of 61 samples including crude peanut oils and refined cottonseeds oils were collected in Ouagadougou, Bobo Dioulasso and surrounding areas. Total Gossypol and p-Anisidine value were determined by spectrophotometry. Peroxide value, acid value, soap residual value and mineral oils were determined by chemical methods. Total oxidation (Totox) value was determined by mathematical prediction. Overall, Gossypol total average of cottonseeds oils analyzed in this study was 0.032%. The p-Anisidine value average was 1.80 for refined cottonseeds oils and 11.65 for crude peanut oils. The Totox averages were respectively 19.37 and 28.36 for refined cottonseeds and crude peanut oils. The average peroxide values for refined cottonseeds oils and peanut crude oils were 8.52 and 8.33 mEq O2/Kg, respectively (p<0.05). The average acid values were 0.27 and 1.95 mg KOH/g for refined cottonseeds oils and crude peanut oils, respectively (p<0.05). None of the oils showed any mineral oil trace. The average residual soap values were respectively 1.47 and 8.32 ppm for peanut oils and cottonseeds oils (p<0.05). The majority values determined conformed to the Codex Alimentarius standard despite some cases of non-compliance. It is essential to improve the processes of oils production and conservation in order to have quality oils to guarantee the health of the consumer.
